| Ships as | Frozen, on dry ice (website) |
| Biosafety level | BSL-2 (website) |
| Donor data provided | Website: 'comprehensive clinical reports', 'clinical metadata intact'. Which fields exactly? |
| Marker panel | TBD – which markers show 'normal' vs activated state? |
| Mycoplasma test | Included – 'mycoplasma-free' (website) |
